7-18
Settings for UDP Mode
When Operation Mode is set to UDP on a serial port’s Operation Modes page, you will be able to configure
additional settings such as Destination address 1 through 4, Local listen port, Packet length, Delimiter
1, Delimiter 2, Delimiter process, and Force transmit.
Destination address 1 to 4
Default
Options IP address range and port (e.g., “192.168.1.1” to “192.168.1.64” and “4001”)
Description In UDP mode, you may specify up to 4 ranges of IP
addresses for the serial port to connect
to. At least one destination range must be provided.
The maximum selectable IP address range is 64 addresses. However, you can enter multicast
addresses in the Begin field, in the form xxx.xxx.xxx.255. For example, enter
“192.127.168.255” to allow the NPort to broadcast UDP packets to all hosts with IP
addresses between 192.127.168.1 and 192.127.168.254.
Local listen port
Default 4001
Options
Description This field specifies the UDP port that the NPort listens to and that other devices must use to
contact the attached serial device.
Packet length
Default 0
Options 0 to 1024
Description This field specifies the maximum amount of data that is allowed to accumulate in the serial
port buffer before sending.
0: Packet length is disregarded and data in the buffer will be sent as specified by the delimiter
settings or when the buffer is full.
1 to 1024: Data in the buffer will be sent as soon it reaches the specified length.
